This is from my reddit post, hope this helps.
Cypro is moderately safe short term, long term not so much. Over time it can cause brain tumors (meningioma, prolactinoma), overall elevates prolactine levels, depletes b12 in your body, can cause depression because it passes blood brain barrier etc.. You can keep using it with EEn for a month or two until levels stabilize, and than taper off slowly. but i'd honestly better stick to EEn mono or include Bicalutamide instead, cause it's relatively safer and more effective with good injection dose.
